Peptides are small chains of amino acids (smaller versions of proteins). Like proteins, peptides are naturally present in foods; natural and synthetic sources of peptides are produced by supplement manufacturers for potential health benefits.
Peptides may be easier for the body to absorb than proteins because they are smaller and may be easier for the body to break down. They can also more easily be absorbed by the skin and intestines, which help them more quickly enter the bloodstream.
Bioactive peptides have different properties and are gained the interest of scientists because of their beneficial properties and positive effects on human health.
